sPECIFIoA'rIoN forming part of Letters Patent No. 647,179, dated April 1o, i900. Application fried March 19,1896. serian. 592,999. (rameau.)

in the county ofrOnondaga and State of New York, have invented certain new and useful Improvements in Lanterns, of which the following is a specification. v j I My invention relates to lanterns; and it contion of parts whereby a better and more desirable lantern can be produced at less cost.` The best methods inwhich I have contemf plated embodying my invention are illustrated` in the accompanying drawings, and my said invention is disclosed in the following description and claims. e

In the said drawings, Figure l is a vertical section of a lantern embodying one form of my invention. base. Figs. 3 and l` show a sideelevation and a plan,respectively, of the spring-lever for 4holding the chimney in position. G are plan and sectional views of the cover of -ing the bail.

Figs. 5 and the top of the chimney.

In the drawings, A designates the` base,

preferably of cast-iron, and B the bail or` frame of wire attached to the base by passing the ends through holes in the saine a short distance, as shown by the dotted lines.l The ends are then slightly flattened, thereby enlarging the wire on two sides, which are then forced back into the holes, firmly secur- The parts of the base that support the bail are thicker than the shell for` the purpose of securing a firm bearing for the bail. By the employment of a wire for the bail which is smaller than the hole in the base the wire maybe readily inserted in the base, and even by iiattening the wire somewhat and drawing it backwardly and upsetting the end of the wire it is possible to verystrongly and cheaply unite the bail to the base, a bail so connected having been found to be very durable and efficient.

Prior to my invention I am not aware that a bail has ever been inserted through holes in the base and secured in said holes as herein provided for.

The bail herein illustrated, starting from the base, is extended upwardly, and at points at or near the upper end of the chimney said bail is bent to form a spring-coil, the handle Fig. 2 is la plan 'view of the` of the ybail being contained between said spring-coils. The spring-coils are represented as nearly circular` in form and the turns of said spring-coils are preferably separated Y' somewhat-say,for instance, alittle in ex `cess ofthethickness of the wire used in the formation of the lever D, carrying thecap to.

be described-thereby enabling said lever to have a compact arrangement or position with relation to thewbail. e e

The bail above the sprin`g-coils B ferredto is represented as bent outwardly at BX, such outward, bend at oneside of the bail acting as a stop to limit the upward movement of the free end of the lever D, said lever moving when the cap His elevated in the direction of thedotted line at the right of Fig. 1.

Thebase is provided witha conicalv socket A', Fig. `l, whereby candles of different dialn- `eters may be used-and rmlysecured.` It is B replacedat the bottom of the base for the purpose of getting the iiame` as low as possible, thereby preventing the upper portion of the duly heated.'` The socket is provided witha closed bottom and is extended upwarda'nd enlarged in a conical or bell shape, forming a reservoir and conductor A, in which the drippings of the lcandle, are caught and conductedinto thesocket, where they may be consumed with safety and economy, as the entire candle `may be utilized).

The base is provided with an elastic bed, on

which the chimney is supported.. The bed in the preferred construction (see Figs. l and 2) is represented' as of rubber plugs or cushions holes, preferably countersunk, on both sides,

The base is provided with a series of openings N, Fig. 2, between the reservoir Al and the chimney C, through which, and also under the chimney, a current of cold air ascends, whereby the chimneyand candle are kept cool and the candle supplied with oxygen, thereby insuring a brilliant light and perfect combustion.

Figs. 3 and 4t show a lever D, which carries a cap or cover for embracingand holding the chimney in position. This lever is represented as composed of a single piece of wire,

having at one of its extremities a coil F of a diameter to fit loosely one arm of the bail,

said coil being retained in operative position on said bail by friction. This lever has, as represented, next said spring-coil F a larger springcoil G, which constitutes a yielding point for the lever, said lever beyond said `spring-coil being extended across from one to the other bail, the free end of the lever beingk bent to constitute, as herein represented, an open loop Gr, which embraces vthe bail, the lever between one and the other arm of the bail havingpivotally mounted upon a part thereof the said cap or cover H, the pivoting of the cap or cover on said lever enabling the latter to adapt itself to variations in length or conliguration of tops of chimneys used.

In order to prevent any distortion of the spring, the handle of the bail is laterally extended and the upward movement of the lever is limited by contact with the bent part B of one part ofl the bail, as shown by the ar- "row,l and when the chimney is removed the lever will rest on the lower part ot'` the coil B.

The pressure of the lever on the chimney is. attained by placing the coil F at an anglev with the lever, and by varying the angle any desired pressure may be maintained.

In applying the lever D to the bail one arm of the bail will be inserted through the coil F j andthe said coil will be. adj listed on the bail to a position substantially opposite the upper end; of the chimney, and when the lever D is raised, so that'it will press the cap I-I carried by itpupon the upper end of the chimney, the coil `is made. to bind or clamp the bail and is thereby maintained frietionally in any desired adjusted position.` l

l H is a thin metal flanged cap or cover for holding the top of the chimney in position. Itjis provided with aseries of openings I vto allow the heat and gases to escape and to create a dra-ft ofair through the chimney.

The cap or cover His carried, as stated, byv

lthe lever D, portions of the wire coil at or near the center. of said lever being loosely jointed to said cap or cover by portions Vcarried by the cap. or cover crossing the wire coils." The center portion ofthe leveris bent or curved, whereby chimneys of slightly-different length may be used and a perfect bearing of the cover on the top of the chimney secured. The cover also permits the use of chimneys with any style of top. I/Vhen the chimney is removed, the free end of the lever D rests on the bottom of the coil B.

This invention is not in all instances limited to the exact form of leverD herein shown, as it is obvious that the shape of the springs might be somewhat modified without departing from my invention, and so, also, the shape of the free end of the lever which embraces or coperates with that leg or arm of the bail of a lantern opposed to the arm or leg upon which the lever has its fulcrum might be varied in shape. I believe that I am the first to use a lever having at one end a coil to cmbrace and be frictionallyheld in position upon one leg ot' the bail, the other end of the lever being capable of coperating with the opposed arm or leg and having a limited extent of motion, said lever being at all times in engagement with the opposed arm or leg, the lever acting normally, owing to its spring shape and properties, to press the cap or cover upon the top of the chimney.

It will readily be seen that oil or other liquid substances may be used by substituting a res ervoir adapted to burn fluids.

What I claim, and desire to secure by Letters Patent, is`

1. In a lantern, the combination with a lever, of ya cap or cover connected with a coil of said lever and connecting with the arms of the lever to be thereby restrained from turning on said lever. y g l 2. In a lantern, the combinationfwithy the bail, of a lever secured at one end to one part of the bail and havingy its .opposite end exthe cap in position, substantially as described.

3. In alantern, a base having holes, combined with a bail composed of a single wire bentk to form a handle, and spring-coils aty points substantially at or near the upper end of the chimney, the free ends of thewire form-V ing said bail being inserted through the holes ofthe base and` upset therein, whereby said bail and means attached to the bail to hold the chimney in place is permanently and se-'.

4. In a lantern, a base having holes, combined with a bail composed of a single Wire erate with the other leg of said bail, said lever having a spring and being restricted in the extent of its vertical movement, and a cap or lcover carried by said lever, substantially as described. l
